Federal Environment and Climate Change Minister Catherine McKenna had her mind blown recently. Remarkably, it had nothing to do with the political gong show south of the border. McKenna was visiting the hilltop monarch butterfly reserves in rural Mexico. There she saw millions of monarchs clinging to oyamel fir trees in mind-bogglingly dense clusters, surprisingly well-camouflaged for such colourful critters. She then wrote a heartfelt article calling on people in Canada to act before monarchs go the way of passenger pigeons and buffalo.
